Can you duplicate modded items?

Does anyone know how to duplicate modded armor or weapons that the modder only placed one in the game? Because i see so many armor that i want to give to all my companions. Example Dragbody Deathstroke helmet...I want to be slade and have all my followers wear slade's mask. Is there a way to get the console code for specific mod items? Any help is appreciated. Thanks

If you use NVSE - you can also just drop the item you need to duplicate on the floor, open console, click on the item, type GBO, you will get unique editorID for that item, and you can just type player.additem xxUniqueID 1xx - number of the mod in your load order. You need to check it first.

Yes you can. Drop the armor you want to duplicate on the ground, open up the console(~), click on the armor on the ground, you'll see a while name popped up, check if that's the correct name for the armor, then type in the console gbo , then it'll give you the armor/items' id, then just use the normal player.additem <id> <quantity>.

You can also go into the GECK and place the item into the game world, as many of them as you'd like, or add a container and put them in it. The GECK also allows you to tweak stats and other neat stuff.
